Description

The M51132 is a VCA (Voltage Controlled Amplifier) IC developed as an electronic volume control for audio-visual

equipment. The IC is used to process small analog signals at the stage before power amplifier. Right/left independent

volume control or right/left simultaneous volume control can be selected by DC voltages. Its built-in pass through

function, in combination with an ALC amplifier, offers the capability of automatic level control.

Features

• Two control modes can be selected.

(Left/right independent volume control mode or left/right simultaneous volume + balance control mode.)

• Pass through switch is included to output the input signal as it is, irrespective of the volume/balance control

voltages.

• Shock noise reduction pin is provided to reduce pass through switch on/off shock noise.

• Built-in reference supply voltage circuit: output current 10 mA (Typ.)

• Maximum input: 3.4 Vrms (Typ.) (f = 1 kHz, THD = 1%)

• Low distortion: 0.005% (Typ.)

• Good channel separation: 102 dB (Typ.) (f = 1 kHz, Vo = 2 Vrms, IHF-A)

Recommended Operating Conditions

• Supply voltage range: Vcc = 8 to 15 V

• Rated supply voltage: Vcc = 12 V
